Abstract
The utility model discloses a connection structure can slide, it includes the steel corbel, the steel corbel welds in the built-in fitting of burying underground in existing concrete structure, the top surface of steel corbel has the oval bolt hole in the corresponding position department reservation of steel structure base's construction bolt, it is fixed with the steel corbel through construction bolt and oval bolt hole that steel structure base passes through. The utility model discloses can allow steel structure base to take place to slide in the horizontal direction (keeping away from or pointing to existing concrete structure) when reliably transmitting steel structure base and transmitting the load to reach the horizontal direction deformation or the displacement that the release steel construction produced at this department's base.
Description
Technical Field
The utility model belongs to the technical field of distributed energy station construction technique and specifically relates to a set up connection structure of steel construction on existing concrete structure.
Background
In the construction of distributed energy station, because of the place restriction, there are pipe support steel construction and support steel construction of setting up on existing concrete structure in a large number. The structure has the advantages of reliable force transmission and convenient installation; the method has the defect that the deformation of the steel structure in the horizontal direction (towards or away from the existing concrete structure) cannot be released at the connecting position due to the adoption of the friction type high-strength bolt. Therefore, it is necessary to provide a new slidable connecting structure for the above problems.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of the horizontal deformation that current connection scheme can not release the steel construction, the utility model provides a connection structure can slide, the load that this structure can not only effectively transmit the steel construction base and transmit can effectively release the steel construction moreover at the deformation of horizontal direction (directional or keep away from existing concrete structure).
The utility model discloses a solve above-mentioned technical problem through following technical scheme:
the utility model provides a connection structure can slide, its characteristics lie in, it includes the steel corbel, the steel corbel welds in the built-in fitting of burying underground in existing concrete structure, the top surface of steel corbel reserves the oval bolt hole in steel construction base's mounting bolt's the corresponding position department, steel construction base and steel corbel pass through mounting bolt and oval bolt hole are fixed.
Preferably, the steel corbel adopts a T-shaped or I-shaped section.
Preferably, butt welding seams are adopted between the steel corbels and the embedded parts.
Preferably, the horizontal sliding direction of the steel structure base is parallel to the major diameter of the oval bolt hole, the minor diameter of the oval bolt hole is not more than do +2mm, and do is the diameter of the mounting bolt.
On the basis of the common knowledge in the field, the above preferred conditions can be combined at will to obtain the preferred embodiments of the present invention.
The utility model discloses an actively advance the effect and lie in:
the utility model discloses can allow steel structure base to take place to slide in the horizontal direction (keeping away from or pointing to existing concrete structure) when reliably transmitting steel structure base and transmitting the load to reach the horizontal direction deformation or the displacement that the release steel construction produced at this department's base.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the present embodiment provides a slidable connecting structure, which comprises a steel bracket 2, an oval bolt hole 3, a mounting bolt 4 and a steel structure base 5. The steel corbel 2 is reliably welded to an embedded part 1 buried in an existing concrete structure 10, and an oval bolt hole 3 is reserved in the position, corresponding to a mounting bolt 4 of a steel structure base 5, of the top surface of the steel corbel 2. The steel structure base 5 and the steel bracket 2 are fixed through the mounting bolts 4 and the oval bolt holes 3. The vertical load and the horizontal load (perpendicular to the sliding direction) transmitted from the steel structure base 5 are transmitted to the existing concrete structure 10 through the connecting welding seam between the steel corbel 2 and the embedded part 1. The steel structure base 5 can slide horizontally in the major diameter direction in the oval bolt hole 3.
Wherein, the steel bracket 2 should adopt a T-shaped or I-shaped section.
Preferably, butt welding seams are adopted between the steel corbels 2 and the embedded parts 1, and if fillet welding seams are adopted, four-side girth welding and full welding are adopted.
It is noted that the length of the oval bolt hole should be directed towards and away from the existing concrete structure 10, and the horizontal sliding direction of the steel structural base 5 is parallel to the long diameter of the oval bolt hole 3. The major diameter of the elliptical bolt hole 3 should meet the requirement of slippage, and the minor diameter of the elliptical bolt hole 3 should be no more than do +2mm (do is the diameter of the mounting bolt 4).
It should be noted that a gap should be reserved between the end of the newly-built steel structure and the existing concrete structure 10, and preferably, the size of the gap is not less than 50 mm.
The available existing concrete structure of newly-built steel construction is as passing the power fulcrum to eliminated the level of newly-built steel construction and to warping or the adverse effect that the displacement produced existing concrete structure, the while is under construction portably, has very strong practicality.
Although particular embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are examples only and that the scope of the present invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
